"Tactics:

Knights can be used to charge the front line of enemy troops, as they have heavy armor and are not that vulnerable to the attacks of enemy infantry.

One of the most effective tactics to use with the Knights is to have your infantry hold ground, creating a defensive wall. When the enemy are advancing towards your infantry, tell your cavalry to follow you and flank to the left or right until you are behind the coming enemy. When they are within charging distance, charge both your cavalry and your infantry at the same time. Timing here can be very important, as ideally both troop divisions need to hit the enemy simultaneously. This attack will greatly weaken the enemy as their attention will be split in two directions at once, halving their combat effectiveness.

It is recommended not to use flanking tactics on a hilly battlefield since the Knights' horses won't be able to run at full speed and will be taken down more easily. Instead, try to let the battle take place on a flat piece of ground or keep your Knights together with your infantrymen."
